Highly efficient power supply and backup power supply solutions to telecommunications, information and industrial technologies.

Remote Power Feeding System modular version DCS-RPS-120 up to 1080W

Compact power supply system DCS-RPS is a complete device designed to supply power to industrial, control, telecommunication and security systems with the use of telecommunication lines. The system allows for transfer of 1080W of power to the distance of up to 5 km. The converter system is powered by 48V DC nominal input voltage, 48V DC nominal output voltage and by maximum transmitted power of up to 1080W.
The DCS-RPS system contains:

  • DC/DC-TPU module: converter from 48V DC to 360V (±180V) DC (central unit–power feeding side).
  • DC/DC- RPU module: Aggregation of supply lines, diode isolation: and down converter from 360V (±180V) DC to 48V DC on the remote side (receiving side / supplied side).
  • MP module: Remote control and monitoring (Ethernet or GPRS)
